What our shortlists say about the one we picked.
Best for: Mid-sized teams wanting one cloud console
It earns its place because detection and response come in the same agent as prevention, so teams that already run Sophos Endpoint can turn on EDR from the Sophos console without a new agent. That suits teams that want one console for endpoints and other Sophos products. Only one integration is listed, so check how it will feed your SIEM if you run one.
